Professional Applications & Engineering Value

These 3/8"-16 UNC flat head screws deliver critical performance advantages in demanding industrial applications where vibration resistance and corrosion protection are paramount. The cadmium-plated alloy steel construction provides superior environmental protection while maintaining the Rockwell C39 hardness required for repeated disassembly cycles. The coarse UNC thread profile ensures rapid installation in structural steel, machinery frames, and heavy equipment assemblies, while the hex drive configuration prevents cam-out issues common in high-torque applications. Engineered to ASTM F835 specifications, these fully threaded screws maintain dimensional stability across temperature variations, making them ideal for aerospace, defense, and industrial manufacturing applications requiring certified components.

Specification Summary & Compliance

Manufactured to Class 3A thread fit tolerances with UNC coarse threading (3/8"-16) and right-hand thread direction. Features include 1" length, 0.781" head diameter, and 82° countersink angle per standard flat head profile. Material certification includes 140,000 psi tensile strength and Rockwell C39 hardness. Complies with ASTM F835 specification (MS24667-52) for dimensional and mechanical properties. The cadmium plating meets industry standards for corrosion protection while maintaining compatibility with RoHS and REACH requirements for industrial use.
